Working on
computers is essential in several professions, while a sizeable number do so
for leisure or communication needs. But very few are aware of the flip side of
working on computers. Computer screens emit a harmful blue light that is
dangerous to human eyes and prolonged usage can lead to what has come to be
known as digital eye strain in medical lexicon.
However, just taking a few simple steps can keep your
eyes from getting strained, irritated and dry despite using your computer all
day long.
Keep
your screen clean
Dirt, dust and fingerprints on the computer screen make
it harder to read what’s on the screen. If you ignore the grime continuously,
it becomes a habit and can lead to chronic headaches in the long run.
Good thing is that this can be easily avoided. Take a
minute out of your schedule and wipe the computer screen daily. It will be enough
to keep your screen regularly cleaned and avoid you the extra strain.
Use
proper lighting
Too much light, either from an internal source or direct
sunlight through a window, causes eye strain as much as seeing on the screen
out in the sun.
Place your computer in a way that the windows are neither
in front or behind it, but on the sides. Absolutely eliminating exterior light
is even better.
Also, avoid working under overhead fluorescent lights. If
that is not possible, at least try switching to "full spectrum"
fluorescent lights which are more comforting for computer work than regular
fluorescent tubes.
Use
fonts that are easy to read
It may sound obvious, but computer screens have a way of
making us forget to blink. It is, in fact, very common to blink less frequently
while working on the computer. But blinking at regular intervals while working
on computers is essential as it moistens eyes and prevents them from dryness
and irritation.
If you still feel dryness or irritation in your eyes,
switch to using lubricating eye drops prescribed by your doctor. And if you
suffer from chronically dry, itchy eyes, then using a laptop instead of a desktop
computer is recommended. When you’re looking down at a laptop, your eyes tend
to stay more moist.
Follow the 20-20-20 rule
Another very simple rule, but also a necessity. All that
you have to do is take a 20 seconds break, every 20 minutes to focus on
something 20 feet away from you.
This simple task will help you maintain a healthy level
of moisture in your eyes, and also reduce eye strain. You can add another 20 to
it by sitting at least 20 inches away from your computer screen.
Segmenting time spent on the device proves to be very
beneficial in the long run.
Annual eye test
Get a comprehensive eye examination conducted at least
once a year. It helps you prevent vision problems if you don’t have them, and
keep a check in case you are already suffering.
A comprehensive eye test is even otherwise an important
barometer of overall health. Risk for things like stroke, diabetes,
cardiovascular disease, brain tumours, aneurysms, and multiple sclerosis can be
evaluated just by testing your eyes.
When you go for the eye test, do inform your doctor how
much you use the computer.
Consider
using computer glasses
It is always a good idea to invest in computer glasses,
because using them reduces strain on your neck, back and eyes. The
anti-reflective or anti-glare coating on their specialized lenses softens the
glare of harsh lights emitted from the computer screens. But you can use
computer glasses only if the doctor has recommended them.
Green
diet
Besides these tips, there are a number of other steps you
can take to keep your eyes fit such as seeing a doctor regularly, and including
dark leafy greens like spinach, broccoli, zucchini, peas etc in your diet. It
is important that prevention and care begins at the right time for eyes. After
all, we can enjoy our gadgets only if our eyes support us.
